I recently made my second purchase from your online catalog, and I just noticed that I set up a different username each time. *I hope this does not cause problems. *My plan is to delete the second username after my second order is shipped. *Is this the best course to take?

Two user names isn't a problem for us. The main reason for a user name on the Online Catalog is to make it easier for you each time you visit. You may delete the profile or just leave it. Which ever is easier for you.
